System Description
The Spirit II 150 is a 150 amp microprocessor controlled, 100% duty cycle high current
density plasma cutting and marking system. It utilizes a precision, dual gas torch that is
capable of cutting mild steel up to 1-1/2" thick and stainless steel up to 1” thick.
The system contains a computer controlled automatic gas console with a touch screen
interface (plasma console). All cutting parameters are controlled through the plasma
console. Setting up a cut is as simple as selecting the material type, material thickness,
and process (cutting or marking). All gas types and pressures are set automatically.
The operator can easily view pictures and part numbers of the torch consumables.
Another screen shows the recommended cutting speed and torch height for making the
cut. These parameters can be transmitted to an X/Y machine controller or an arc
voltage control system via RS-422 serial communication. The RS-422 port also allows
for full control of the cutting parameters from an x/y machine controller. The system
keeps a detailed record of errors that may have occurred during the cutting sequence.
Additionally, systems utilizing the automatic gas console can use argon for marking,
which produces improved mark quality.
The Spirit II system is available with an Arc Starting Console (ASC) that utilizes
CleanStrike
™
technology, which results in reduced EMI and thereby minimizes
interference with sensitive electronic equipment.
For cutting mild steel, the system uses oxygen for the plasma gas and either oxygen or
air for the shielding gas. When cutting stainless steel or other non-ferrous materials, air
or H17 (17.5% hydrogen, 32.5% argon, 50% nitrogen) is used for the plasma gas and
either air or nitrogen is used for the shielding gas. Oxygen and nitrogen are used for
the preflow and postflow gases.
The torch is water-cooled and consumables are machined to exacting dimensions and
checked with the latest computerized measuring systems. Five nozzle sizes (30, 50,
70, 100, and 150 amps) are available to produce excellent cut quality throughout the
cutting range.
Each enclosure in the system is rated for IP21S sealing, which is intended for
indoor use only. The system is not suitable for use in rain or snow.
Systems containing an ASC with CleanStrike
™
Technology are only
recommended for use with downdraft cutting tables.
